Metabolic Pathways
Enzymes
The active site has a high affinity to the substrate and products have a low affinity which enables it to leave
As the substrate concentration increases, the enzyme concentration increases until all of the active sites are full from substrates. Adding more substrate makes no difference to the reaction rate
All metabolic pathways have to be regulated and controlled to stop the build-up of an end product that isn't needed

An induced fit occurs where the active site changes slightly to better fit the substrate after it binds

Enzymes change the substrate at each step in the metabolic pathway in order to get the final product at the end

If a specific enzyme or substrate isn't available then an end product can still be made using an alternative route, e.g. the sorbitol route when there is too much sugar present
